“A Wild Last Boss Has Appeared!” is a hugely popular dark fantasy series that has surpassed 1.4 million total copies. The original work is by Enzu, with original illustrations and character designs by YahaKo (published by Earth Star Novel, Earth Star Entertainment), and a manga adaptation by Hazuki Tsubasa.

In the year 2800 of the Midgard calendar, Lufas Maphaahl, feared by the people as the “Black Winged Overlord,” saw her path of conquest come to an end after a fierce final battle against the heroes known as the “Seven Heroes.” It seemed that an era of peace would dawn with the Overlord sealed away, but… as the balance of power crumbled, the world found itself exposed to the threat of the Demon God Tribe.

200 years later, in an attempt to counter the Demon God Tribe, humanity tries to summon a new hero. However, the one who appears is none other than the Overlord Lufas herself, awakened from her long sealing!
